Subsequently, it will be published following the linked data principles, specifically in the RDF format. Sparqk the paper, we make use of publicly available structured records from a digital archive catalogue, and we demonstrate a principled approach to converting the records into semantically rich and interlinked resources for all to reuse.

The information contained in these data sets will be enriched with information in other sources such as DBpedia, esDBpedia and OpenStreetMap. First, one has to know the semantic concepts and the type of knowledge contained in an endpoint a-priori in order to query content effectively.


The linked data Web provides a simple and flexible way of accessing information resources in a self-descriptive format. This is a fundamental pillar of the Semantic Web. However, this data is still largely limited to be used up by domain professionals and users who understand Linked Data technologies. Virtuoso, by OpenLink Software, is a modern enterprise-grade solution Get label if it exists?

For a given client, it solely returns the permitted data for the requested query, defined via a flexible policy language that combines the RDF and SPARQL standards for policy definition. You may open a separate column?
